Question

修改。 2015-30-10。我试过这个：

../configure --prefix=/usr/local/GNU-CROSS/binutils-2.25.1/ CC="clang -fembed-bitcode -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS8.4.sdk -Wno-error -Wno-implicit-function-declaration -mios-version-min=8.4 -no-integrated-as -arch arm64 -target arm64-apple-darwin" CPP="clang -E" CPPFLAGS="-fembed-bitcode -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS8.4.sdk -Wno-error -Wno-implicit-function-declaration -mios-version-min=8.4 -no-integrated-as -arch arm64 -target arm64-apple-darwin" --host=aarch64-apple-darwin --disable-assembly --enable-static --disable-shared
make -j 4

配置没问题，但make触发了这个：

BFD does not support target aarch64-apple-darwin

最初的问题。

我正在尝试为iOS（8.4）64位目标交叉构建binutils 2.25.1。我把binutils-2.25.1文件夹放在目标上，config.guess脚本给了我arm64-apple-darwin14.0.0。在我的主机（x86_64-apple-darwin14.4.0）上，我在binutils-2.25.1中创建了一个build文件夹并在那里运行：

CCFLAGS="--arch arm64" LDFLAGS="--arch arm64" ../configure --prefix=/usr/local/lvm-cross/ --host=arm-apple-darwin

给了我这个：

configure: error: in `/Users/XXXX/Documents/src/gcc-5.2.0-cross/binutils-2.25.1/build':
configure: error: C compiler cannot create executables

所有详细信息都在最后的config.log文件中。

我的问题如下：如何为这个64位目标构建binutils？

config.log文件包含：

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.64.  Invocation command line was

  $ ../configure --prefix=/usr/local/lvm-cross/ --host=arm-apple-darwin

Answer 1

TL; DR：我认为您可能永远不会看到针对iOS的任何binutils版本。

Apple从未在iOS上制作Mach-O的规格。
您不太可能将包含libbfd的代码添加到App Store中（因为明确指出GNU GPL与App Store规则根本不兼容，尤其是在VLC for iOS争议中）。
您不太可能将使用Apple的clang版本以外的任何代码编译到App Store中（App Store审查指南明确禁止）
即使针对OS X，binutils也无法实际链接和构建代码。

如果您的目标是iOS，则必须使用Apple提供的工具链，或者从Apple发布的源代码构建您自己的等效代码（ld，clang和LLVM都是开源项目虽然底层的iOS库可以从Mac上复制，但仅供您个人使用）。

跨越建筑binutils 2.25.1 for iOS8.4（arm64-apple-darwin14.0.0）
